JJ still hasn't secured a spot mathematically. She is 3860. And Kerber can get to 3905 if she wins Moscow. If Jankovic fails to win Beijing, reach semis of Osaka or QF of Moscow, she would be stuck at 3860.

The top 7 have officially qualified and only Kerber can still overtake # 8 Jankovic. Jankovic needs 46 points to secure #8 , so she has to either win Beijing or semi in Osaka or quarter final in Moscow.
